Transfer Radiation Thermometers

The HEITRONICS Transfer Radiation Thermometer (TRT) is for use as a Transfer Standard of the highest level at NMIs (National Metrological Institute). It provides a high quality accurate transfer of temperatures to user's Black Body Radiators (BBRs), after the TRT is calibrated against NMI fixed-point Black Body Radiators.

For convenient and scientific use of the TRT, the user has access to the major features and values at the TRT by using PC-based software.

The Heitronics TRT series is available in three models with spectral ranges of 3.9um and 8-14um covering the temperature range of -50 to +1000°C.

Model Spectral Range Temperature Range Typical Field of View



-50 to +300°C

150 to 1000°C

6.8mm @ 380mm

5.5mm @ 360mm

TRT-IV.82 8-14um -50 to +1000°C 6.8mm @ 380mm
TRT-IV.41 3.9um 150 to +1000°C
